Added support for right-to-left shimmer

[mattlogan]

Hey there!

Nice library. I just added another styleable attribute called shimmerDirection to let the user decide the direction of the shimmer movement. It works just like LinearLayout's "layoutDirection" attribute.

Hmm interesting but I'm not sure I want to set that at the view level. It's a property related to the animation and not to the view itself. Right now the ShimmerTextView has no idea it's animating.

I was planning to convert my Shimmer.animate() to a builder and add that kind of feature.

Thanks for the PR anyway. I'll see what I can do tomorrow.

linking that to #4

It makes sense that it's a property of the animation, not the view. In MainActivity you would then have something like Shimmer.animate().rightToLeft(), or Shimmer.animate().direction("rtl").

I just thought it would be easy for the user to define the shimmer direction in the same place they set the text and color (in the xml), but your explanation makes more sense from a design standpoint.

fixed in version 1.1.0
